Enables adenylate cyclase binding activity; neuropeptide binding activity; and small GTPase binding activity. Involved in several processes, including activation of phospholipase C activity; cAMP-mediated signaling; and positive regulation of intracellular signal transduction. Located in several cellular components, including bicellular tight junction; caveola; and rough endoplasmic reticulum. Biomarker of cystitis. Orthologous to human ADCYAP1R1 (ADCYAP receptor type I).
